Not sure if this is necessary:

$ grep 'tty|input' /etc/group
tty:x:5:
input:x:97:

The elogind service ought to be in boot runlevel according to the wiki:

Have you followed this wiki page to configure your kernel, include the 
appropriate firmware for your card(s), set up INPUT_DEVICES & VIDEO_CARDS in 
make.conf, emerge associated x11-base/xorg-drivers and the x11-base/xorg-
server packages before a reboot?

https://wiki.gentoo.org/wiki/Xorg/Guide

There should be a fb0 device listed:

$ ls -l /dev/fb*
crw-rw---- 1 root video 29, 0 Jun 14 08:52 /dev/fb0

You'll also need to have emerged a Desktop Environment, or at least a window 
manager:

Check the above wiki pages and post back with any queries and accompanying 
logs if things do not work as expected.
